I think you should add a.i in the game because it would create a more futureistic game were you have these a.i that help you out in combat they give you ability’s the can give you speed strength or sight increases. I would really make the game more competitive and you could have abilities that make a shield around you things like that would make the game more interesting and tactical. They could also give information about the battle how many are alive or dead or who’s winning.
Pretty much everything you asked for is already in Halo 5 in some way. The score tells you who is winning, the player roster and waypoints tells you who is alive or dead. Your AI squadmates in campaign support you. You can get speed boosts, power boosts, overshields, or active camo in Warzone and some Arena maps. Loadout variants in Warzone allow you to get different gun sights and gun functions.
If you have suggestions about what you’d like to see in Halo 6, you’ll find links to some active wishlist threads in my signature that you can contribute to.
